Which verse was revealed in response to the disbelievers' denial of the Messenger being a human being, and in which Surah is it?

Al-Wahidi said that the two verses: "And We sent not before you except men to whom We revealed" (Yusuf: 109), and "Has it become a wonder to the people that We revealed to a man from among them, [saying], 'Warn the people'" (Yunus: 2), were revealed because the polytheists of Makkah denied the prophethood of Muhammad, peace and blessings be upon him, and deemed it improbable that the Messenger could be a human, saying: "Allah is too great for His Messenger to be a human."
